Hello,

This is the first RFC of the patch set that converts the internal
Buildroot toolchain backend to the package infrastructure. It converts
elf2flt, the kernel headers, the gcc and the uclibc build logic to
packages.

The code is also available from:

   git://git.free-electrons.com/users/thomas-petazzoni/buildroot.git toolchain-infra

Summary of the patches:

 * Patches 1 to 6 are cleanup / preparation patches. They can be
   applied right now (which would help reduce the size of this patch
   set).

 * Patch 7 converts elf2flt to the package infrastructure.

 * Patch 8 converts the kernel headers to the package infrastructure.

 * Patch 9, 10 and 11 introduce the gcc-initial, gcc-intermediate and
   gcc packages. At this point, they are not used by Buildroot.

 * Patch 12 switches the toolchain build logic to use the gcc-initial,
   gcc-intermediate and gcc packages, and removed the toolchain/gcc
   code.

 * Patch 13 makes a small optimization to the size of the sources
   extracted for gcc.

 * Patch 14 converts uClibc to the package infrastructure.

 * Patch 15 to 18 make some followup cleanups.

Some comments:

 * This patch set completely removes the support for building the
   toolchain on the target (i.e the new gcc package and uClibc package
   do not support building/installing the target variant). A cleanup
   patch at the end of the series removes BR2_HAVE_DEVFILES.

 * The gcc-initial, gcc-intermediate and gcc packages each extract
   their own copy of the gcc sources. With the previous code,
   out-of-tree builds were used to share the tree, but moving to the
   package infrastructure makes this more difficult. Since the build
   is still done in a sub-directory called 'build' inside each source
   directory (because gcc does not support in-tree build), I've tried
   to symlink the source directories, and create separate build
   sub-directories (build-initial, build-intermediate, build-final),
   but the problem comes with the stamp files, that would have the
   same name and location for the gcc-initial, gcc-intermediate and
   gcc packages.

   In order to mitigate this additional amount of work and disk space
   consumption, I've added a little optimization to the gcc sources
   extraction, by not extracting the libjava, libgo and gcc/testsuites
   directories. This reduces approximately by half the size of the gcc
   sources.

 * The code of the gcc-initial, gcc-intermediate and gcc packages
   could benefit from some factorization. For now, they are completely
   independent from each other. I've tried doing some factorization
   like GCC_INITIAL_SITE = $(GCC_SITE), but ran into issues (like
   GCC_SITE not being defined by the time GCC_INITIAL_SITE uses it or
   something like that). This is an area where a bit of
   help/suggestions would be welcome.

 * I've tested a few configurations like minimal ARM toolchain,
   full-blown ARM toolchain, ARC toolchain, but I certainly haven't
   tested all configurations. Don't hesitate to test this patch set
   with your existing configurations and report success/issues.

 * I haven't converted the code that installs the uClibc testsuite,
   even though the corresponding Config.in option is still
   there. Doing this conversion is on my TODO-list.

 * The uClibc code to mungle the .config has been heavily
   reworked. Some of the logic has been moved to the Config.in file,
   when it allows to more easily calculate the configuration values.

For information, the sequence of steps when building is now:
